Come usare Protect PDF Files (and Merge PDF Pages Too) in Seconds
- Drop your PDF in. Drag the file straight from your downloads folder into the dropzone, or click to browse. Works with single files or merged study packs.
- Set a password. Pick a strong password you'll actually remember. This is what readers will need to open the document.
- Choose permissions. Toggle whether others can print, copy text, or edit the file. Lock it all down for sensitive work, or leave printing on for handouts.
- Apply protection. Hit the protect button and the tool encrypts your PDF locally in your browser — no uploads, no waiting in a queue.
- Download and share. Save the protected copy and send it off. The original stays untouched on your device in case you need to tweak settings later.
